FIELD OF THE INVENTION

The present invention relates generally to modular wall systems for temporary installations.

BACKGROUND OF THE INVENTION

Temporary walls or partitions are often used at construction sites, such as renovation or remodeling projects in malls, hotels, office buildings and other public or private venues. These walls provide a safety and security barrier while the renovation or remodeling project is in progress. They may also block dust and noise from entering public spaces on the other side of the wall. Typically, temporary walls or partitions are constructed on site using traditional building materials, such as lumber and drywall or plywood. This is costly, time-consuming and creates debris. Additionally, such temporary walls are difficult to reuse after no longer being needed at a particular location.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention provides several embodiments of a wall panel system including interlocking wall panels, as well as methods for making such interlocking wall panels. Referring to FIG. 1, a wall panel system is shown generally at 10. It includes a base track 12 and a plurality of interlocking wall panels 14 that are received on the base track and interlock with one another so as to form a generally continuous wall. A top track 16 may be received on the upper end of the wall panels 14 and braces 18 may be used for stabilizing the wall panel system or interconnecting it with other structures. The wall panel system may be used as a temporary wall system around construction or remodeling sites, or as wall panels to form a temporary enclosure, such as at a tradeshow.

FIG. 2 shows a portion of a base track 12, two wall panels 14, and a portion of a top track 16. As shown, the base track is an extruded, elongated track having a generally flat bottom piece 18 and two upwardly extending flanges 20 and 22. The flanges 20 and 22 are spaced apart so as to define a receiving channel 24 that receives a bottom edge of the panels 14. In order to assemble a wall panel system, the base track 12 is first placed on a surface such as a floor, and then a first wall panel 14 is placed into the channel 24. A second wall panel 14 is then placed in the channel adjacent the first panel and the panels are slid together, such that a tongue 26 of one panel engages the groove 28 of the adjacent panel. In some versions, the top track 16 is an identical component to the bottom track 12 and is received on the upper edges of the panels 14.

Each wall panel may be said to have a top end 30 and a bottom end 32 that each extend between a pair of opposed edges 34 and 36. In the typical configuration, the top end 30 forms the top of the panel, the bottom end 32 forms the bottom of the panel, and the edges 34 and 36 form vertically extending side edges. However, positions such as top, bottom, and side are relative and are used for description purposes only. They are not limiting on the invention. As shown, the groove 28 is formed in one of the edges 34 and the tongue 26 extends from the other edge 36. The panels 14 may also be said to have a front face 38 and an opposed rear face 40.

Referring to FIGS. 3-5, one embodiment of an interlocking wall panel in accordance with the present invention will be described in more detail. FIG. 3 shows a portion of one of the panels 14 corresponding to the upper left edge with respect to FIG. 2, and FIG. 4 shows a portion corresponding to the upper right corner with respect to FIG. 2. FIG. 5 shows a top view. Each panel 14 includes a first elongated vertical extrusion 42 and a second elongated vertical extrusion 44. Each of these extrusions defines an edge of the panel and has a length corresponding to the height of the panel. In preferred embodiments, the extrusions 42 and 44 are identical to each other. Referring to extrusion 42, the extrusion has a front face 46 and an opposed back face 48. Each of these faces is generally flat and parallel to one another. The faces are spaced apart by an extrusion thickness T1. The extrusion 42 has a left side 50 and a right side 52. In the illustrated embodiment, a groove 54 is defined in the left side 50 and the tongue 56 extends from the right side 52, though this may be reversed. In some versions, the tongue 56 is solid while the remainder of the extrusion 42 is hollow. The main body of the extrusion 42 may be said to have a width W. In one version, the width W is approximately one inch and the thickness T1 is approximately one inch. In an alternative version, the width W is approximately 2 inches.

The panel 14 further has a planar panel body 60 having a front face 62 and an opposed back face 64 that are generally flat and parallel of each other. The front face 62 and back face 64 are spaced apart by a panel body thickness T2. Preferably the thickness T1 and the thickness T2 are the same. The planar panel body 60 may also be said to have a left edge 66 and a right edge 68. A top edge 70 extends between the edges 66 and 68 and, when the panel is assembled, may define the top end of the panel 14. Likewise, a bottom edge, not shown, of the planar panel body 60 may define the bottom end of the assembled panel. A front skin 72 and a back skin 74 cover the front and back faces, respectively, of the extrusions 42 and 44 and the planar body 60. When assembled, as shown in FIG. 5, the front skin 72 continuously covers the front faces of the panel body and the first and second extrusions, so as to provide a smooth, continuous and planar front surface for substantially the entirety of the panel. Likewise, the back skin 74 continuously covers the back faces of the panel body and the first and second extrusions so as to provide a smooth, continuous and planar rear surface for substantially the entirety of the panel.

In some versions, the planar panel body is formed of polypropylene, preferably in the form of a honeycomb, while the extrusions 42 and 44 are aluminum extrusions, and the front skin 72 and rear skin 74 are sheets of plastic, such as polystyrene or ABS. In some versions, the front skin 72 and back skin 74 have a thickness of approximately 0.060 inches. This forms a panel that is both reusable and made of recyclable components. The front skin 72 and back skin 74 both provide a smooth surface that may be printed upon or may have advertising adhered thereto, and also is easily cleaned. As known to those of skill in the art, each of the components of the wall panel may be formed by extrusion. The planar panel body 60 and the skins 72 and 74 may be formed by other processes as well. In some embodiments, the components are attached to one another using adhesive on the inner surfaces of the skins. As shown, the planar panel body may have smooth edges 66 and 68, such that the tongue 56 of the extrusion 42 sits against the edge 66, but does not extend into the panel body 60. Alternatively, a groove may be formed in the planar panel body to receive the tongue 56.

In some versions, the assembled panel 14 has an unfinished top and bottom end. That is, the panel body 60 and extrusions 42 and 44 are exposed at the top and bottom ends of the panel; there is no cap or covering piece. As such, these versions consist of only five components: two extrusions, two skins, and a panel body. If adhesive is counted, only 6 components are required. The two extrusions may be identical and the two skins may be identical such that a panel may be constructed using only three part types, plus adhesive.

Referring now to FIGS. 6-9, an alterative embodiment of an interlocking wall panel will be described. The wall panel 80 is formed by interconnecting a first panel member 82 and a second panel member 84. Each panel member 82 and 84 is extruded as a continuous and unitarily formed piece. As such, an entire wall panel can be formed by interconnecting two extruded pieces. In some versions, no adhesive is required. Therefore, each panel consists of only two elements, each of which may be formed from the same material.

The first panel member 82 has a first face portion 86 with an outer surface 88 defining a first face of the finished panel. The first face portion also has an opposed inner surface 90. A shown, this first face portion is a large, generally planar, member. It extends substantially the entire height and width of a finished panel. The first face portion may be said to have a first edge 92 and an opposed second edge 94. An edge portion 96 is interconnected with and integrally formed with the first edge 92 of the first face portion 82. This edge portion 96 defines an edge of the assembled panel and, in this version, has an elongated tongue 98 extending therefrom.

The second panel member 84 has a second face portion 100 with substantially identical dimensions to the first face portion 86. The second face portion has a first edge 102 and an opposed second edge 104. It also has an outer surface 106 that defines the second face of an assembled panel. The second face portion 84 also has an opposed inner surface 108. An edge portion 110 is interconnected with and integrally formed with the first edge 102 of the second face portion 84 and defines an edge of the finished panel. The edge portion 110 in this version includes an elongated groove 112 defined therein. As with the earlier embodiments, the tongue 98 and groove 112 are configured so as to interconnect. The may have different shapes and dimensions than illustrated.

The first panel member 82 and second panel member 84 are preferably interconnected by a plurality of connection members provided on each panel member. In the illustrated embodiment, a plurality of connection members 114 extends from the inner surface 90 of the first panel member and a plurality of connection members 116 extend from the inner surface 108 of the second panel member 84. The connection members 114 and 116 are configured so as to interconnect with one another, thereby locking the first panel member 82 to the second panel member 84 and forming a finished panel. The connection members may take any form. In FIG. 9, the connection members may take the form of individual connection members located across both the width and height of the panel members. The connection members 114 may take the form of tube-shaped elements, each having a base 118 connected to the inner surface 90 of the first panel member 82 and an outer end 120 with the connecting feature defined thereon. The connecting feature takes the form of an inwardly extending flange 122 in the open end of the outer end 120 of the tube-shaped element. The connection member 116 may take the form of a pillar-shaped element having a base 124 connected to the inner surface 108 of the second panel member 84 and an outer end 126 with a connecting feature defined thereon. The connecting feature takes the form of a tip 128 with an undercut side. This tip 128 is configured to engage the opening in the end of the connection member 114. In order to form the panel members as shown in FIG. 9, a special extrusion method is used that allows the creation of the connection members at periodic intervals along the extrusion direction as the panel members are extruded.

FIG. 10 illustrates an alternative version in which the connection members take the form of elongated ribs that extend along the extrusion direction of the panel. This approach utilizes more traditional extrusion methods. The connection members 130 on one of the panel members takes the form of an elongated rib having a base 132 connected to the inner surface and an outer end 134 with a connecting feature defined thereon. In the illustrated embodiment, the connecting feature takes the form of a tip with an undercut side. The corresponding connection members 136 on the other panel member each take the form of a pair of spaced-apart ribs 138 and 140 with a slot 142 defined therebetween. The slot is configured to receive one of the ribs 130. The slot may have a connecting feature at its outer end. In the illustrated embodiment, the connecting feature takes the form on inwardly extending flanges 144 at the top of the slot 142.

Some embodiments of the present invention may further include a feature for supporting the second edge 94 or 104 of a panel member. Referring to FIG. 6, a ledge 150 is shown extending from an inward surface of the edge portion 110 positioned so as to receive and support the second edge 94 of the panel member 82. This may help to align the edges of the panel members for a uniform appearance. This ledge 150 may be considered a receiver for receiving the second edge 94. It may also be provided for the other second edge 104.

Referring to FIG. 7, an alternative approach is illustrated. Here, a ledge 152 is provided along with a catch 154. The edge 104 is shaped so as to be received on top of the ledge 152 and behind the catch 154. Other approaches are also possible. Adhesive or other connection features may also be used.

As best shown in FIG. 8, the assembled panel 80 may be said to have a completely closed perimeter in a horizontal cross-section. FIG. 8 may be said to represent a horizontal cross-section of the dissembled panel and the entire perimeter of this cross-section is closed, as in having no gaps. In some versions, the top and bottom ends of the assembled panel are open to the hollow interior, as shown in FIG. 8. No cap or finishing piece is used. Instead, the top and bottom tracks cover these openings.
